RE: Welcome to Club SAITO !
I have a question for you guys. I have a well broken in Saito 150 that has been a real trooper for the past couple of years. Recently I started having a problem with the engine at high throttle. It seems to load up and gradually drop RPM until it quits (fortunately my Super Stearman has survived the dead stick landings). The engine starts easily and peaks at about 8500 rpm with a 16x8 Master Airscrew Classic Series prop. After I richen the engine about 400 RPM, the RPM gradually decays until it dies around 6500 RPM. I thought it was too rich, but as I try to lean the engine it quickly becomes too lean and dies. If I try richening the high end more than about two turns out from closed, it loads up and dies. I have changed fuel tanks, all fuel tubing and the glow plug with no improvement. I also tried leaning the low end, but no luck. Any ideas of what I'm missing (besides good engine tuning skills)? Thanks in advance for any help!
